如何将div内的文本复制到剪贴板?我有一个div，需要添加一个链接，将文本添加到剪贴板。有解决办法吗?
<p class="content">Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s</p>
<a class="copy-text">copy Text</a>
在我点击复制文本，然后我按Ctrl + V，它必须被粘贴。

换行(阿尔瓦罗·蒙托罗回答的延伸)
var ClipboardHelper = {
copyElement: function ($element)
{
this.copyText($element.text())
},
copyText:function(text) // Linebreaks with \n
{
var $tempInput = $("<textarea>");
$("body").append($tempInput);
$tempInput.val(text).select();
document.execCommand("copy");
$tempInput.remove();
}
};
ClipboardHelper.copyText('Hello\nWorld');
ClipboardHelper.copyElement($('body h1').first());

这是复制内容的最简单方法
<div id="content"> Lorepm ispum </div>
<button class="copy" title="content">Copy Sorce</button>
function SelectContent(element) {
var doc = document
, text = doc.getElementById(element)
, range, selection
;
if (doc.body.createTextRange) {
range = document.body.createTextRange();
range.moveToElementText(text);
range.select();
} else if (window.getSelection) {
selection = window.getSelection();
range = document.createRange();
range.selectNodeContents(text);
selection.removeAllRanges();
selection.addRange(range);
}
document.execCommand('Copy');
}
$(".copy").click(function(){
SelectContent( $(this).attr('title'));
});
没有flash或任何其他要求的更好方法是clipboard.js。你所需要做的就是在任何按钮上添加data-clipboard-target="#toCopyElement"，初始化它new Clipboard('.btn');它会将id为toCopyElement的DOM内容复制到剪贴板。这是一个片段，通过链接复制您的问题中提供的文本。
虽然有一个限制是它不能在safari上运行，但它可以在所有其他浏览器上运行，包括移动浏览器，因为它不使用flash
$(函数(){ 新剪贴板(“.copy-text”); })； < script src = " https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js " > < /脚本> < script src = " https://cdn.jsdelivr.net/clipboard.js/1.5.12/clipboard.min.js " > < /脚本> <p id="content">Lorem Ipsum只是印刷排版行业的假文本。自16世纪以来，Lorem Ipsum一直是行业标准的虚拟文本 <a class="copy- Text " data-clipboard-target="#content" href="#">copy Text</a>
jQuery简单解决方案。
应由用户点击触发。
$("<textarea/>").appendTo("body").val(text).select().each(function () {
document.execCommand('copy');
}).remove();

从2023年开始，你应该使用剪贴板Api。
navigator.clipboard.writeText('text here you want to copy').then(function () {
alert('It worked! Do a CTRL - V to paste')
}, function () {
alert('Failure to copy. Check permissions for clipboard')
});

纯JS，没有内联onclick，配对类“内容-复制按钮”。如果你有很多元素，会更舒服)
(function(){ /* Creating textarea only once, but not each time */ let area = document.createElement('textarea'); document.body.appendChild( area ); area.style.display = "none"; let content = document.querySelectorAll('.js-content'); let copy = document.querySelectorAll('.js-copy'); for( let i = 0; i < copy.length; i++ ){ copy[i].addEventListener('click', function(){ area.style.display = "block"; /* because the classes are paired, we can use the [i] index from the clicked button, to get the required text block */ area.value = content[i].innerText; area.select(); document.execCommand('copy'); area.style.display = "none"; /* decorative part */ this.innerHTML = 'Cop<span style="color: red;">ied</span>'; /* arrow function doesn't modify 'this', here it's still the clicked button */ setTimeout( () => this.innerHTML = "Copy", 2000 ); }); } })(); hr { margin: 15px 0; border: none; } <span class="js-content">1111</span> <button class="js-copy">Copy</button> <hr> <span class="js-content">2222</span> <button class="js-copy">Copy</button> <hr> <span class="js-content">3333</span> <button class="js-copy">Copy</button>
旧的浏览器支持:
(function(){ var area = document.createElement('textarea'); document.body.appendChild( area ); area.style.display = "none"; var content = document.querySelectorAll('.js-content'); var copy = document.querySelectorAll('.js-copy'); for( var i = 0; i < copy.length; i++ ){ copyOnClick(i); } function copyOnClick(i){ copy[i].addEventListener('click', function(){ area.style.display = "block"; area.value = content[i].innerText; area.select(); document.execCommand('copy'); area.style.display = "none"; var t = this; t.innerHTML = 'Cop<span style="color: red;">ied</span>'; setTimeout( function(){ t.innerHTML = "Copy" }, 2000 ); }); } })(); hr { margin: 15px 0; border: none; } <span class="js-content">1111</span> <button class="js-copy">Copy</button> <hr> <span class="js-content">2222</span> <button class="js-copy">Copy</button> <hr> <span class="js-content">3333</span> <button class="js-copy">Copy</button>
